Qualquer trabalho de carácter académico ou científico deverá incluir uma identificação das fontes consultadas, realizada através de citações no texto e de uma lista final das respectivas referências bibliográficas.
O estilo IEEE (Institute of Electrical and Electronics Engineers) é um sistema de citação numérico aplicado nas áreas da eletrónica, tecnologias, computação, energias sustentáveis, comunicação, robótica, engenharias e tecnologias aplicadas.
Como criar referências bibliográficas a partir do estilo IEEE?
Apresentamos de seguida, uma parte do documento “General Manuscript Preparation” do IEEE .
A numbered list of references must be provided at the end of the paper. The list should be arranged in the order of citation in text, not in alphabetical order. List only one reference per reference number.
In text, each reference number should be enclosed by square brackets. Citations of references may be given simply as “in  …”, rather than as “in reference  …”. Similarly, it is not necessary to mention the authors of a reference unless the mention is relevant to the text. It is almost never useful to give dates of references in text. These will usually be deleted by Staff Editors if included.
Footnotes or other words and phrases that are not part of the reference format do not belong on the reference list. Phrases such as “For example,” should not introduce references in the list, but should instead be given in parentheses in text, followed by the reference number, i.e., “For example, see .”
Sample correct formats for various types of references are as follows.
 G. O. Young, “Synthetic structure of industrial plastics,” in Plastics, 2nd ed., vol. 3, J. Peters, Ed. New York: McGraw-Hill, 1964, pp. 15–64.

E. References—Electronic Sources
The guidelines for citing electronic information as offered below are a modified illustration of the adaptation by the International Standards Organization (ISO) documentation system and the American Psychological Association (APA) style. Three pieces of information are required to complete each reference: 1) protocol or service; 2) location where the item is to be found; and 3) item to be retrieved. It is not necessary to repeat the protocol (i.e., http) in Web addresses after “Available” since that is stated in the URL.
